Hello,
after successfully setting up the application according to the steps from README (for ekuOJ
and for OJL3
), when a user enters /
path in their browser, the following error occurs:
Internal Server Error: /
Traceback (most recent call last):
File "/usr/local/lib/python3.4/dist-packages/django/db/backends/utils.py", line 65, in execute

return Database.Cursor.execute(self, query, params)
sqlite3.OperationalError: no such table: main_contest
The above exception was the direct cause of the following exception:

Any ideas how to fix this?
Thanks!
If the contest does not exist, a Contest.DoesNotExist
exception is raised
Currently, there is no queuing mechanism which ensures that users' submissions run sequentially. This can give all users TLE
if they all submit at the same time.
Add a feature such that every problem can have tags associated with it. These tags will be shown on the problem's page. Clicking on a tag will enlist all problems associated with that tag.
Currently a user can submit solutions to a problem as many times as the user wants and as frequently as the user wants. This can help the user brute force an answer and maybe perform a DOS attack.
The current naming convention of PASS
, CMPLE
, FAIL
for a submission isn't descriptive enough. Have a priority for each test case status and use that to decide submission status if different test cases give different statuses.
